I am a beginner of Selenium.Now I have a website must access by IE (Chrome or Edge do not support it at all).
As Microsoft remove IE in the newest Windows, the website can only access by Compatibility (IE) Mode in Edge.
Here is my code:
var options = new InternetExplorerOptions
{
IgnoreZoomLevel = true,
IntroduceInstabilityByIgnoringProtectedModeSettings = true,
EnsureCleanSession = true,
PageLoadStrategy = PageLoadStrategy.Normal
};
IWebDriver driver = new InternetExplorerDriver($@"{AppDomain.CurrentDomain.BaseDirectory}IEDriverServer.exe", options);
driver.Manage().Window.Maximize();
driver.Manage().Timeouts().AsynchronousJavaScript = TimeSpan.FromSeconds(60);
driver.Navigate().GoToUrl("https://cced.com/cced.aspx");
Debug.WriteLine(driver. Title);
After the program ran, it opens Edge browser and accesses the homepage of the website by IE mode successfully.
However, even I add a breakpoint to the line Debug.WriteLine(driver. Title); it never runs.
After 1 minute, it reports an error like this:
OpenQA.Selenium.WebDriverException
HResult=0x80131500
Message=The HTTP request to the remote WebDriver server for URL http://localhost:9324/session/700c0df3-fcf5-459e-a9d9-0487cfd42d15/url timed out after 60 seconds.

What’s wrong with it?
The right way to automate IE mode is defining InternetExplorerOptions with additional properties that point to the Edge browser. You need to set ieOptions.AttachToEdgeChrome property to true, and ieOptions.EdgeExecutablePath to the path of the Microsoft Edge executable.
Please refer to the following steps:
- Download IEDriver and make sure that the version of IEDriver that you download is 4.0.0.0 or greater.
- Meet the requirements for Selenium’s required configuration.
- Place the IEDriver executable in your PATH.
- Sample code to automate IE mode:
using System;
using OpenQA.Selenium;
using OpenQA.Selenium.IE;
namespace IEDriverSample
{
class Program
{
static void Main(string[] args)
{
var ieOptions = new InternetExplorerOptions();
ieOptions.AttachToEdgeChrome = true;
//change the path accordingly
ieOptions.EdgeExecutablePath = "C:/Program Files (x86)/Microsoft/Edge/Application/msedge.exe";
var driver = new InternetExplorerDriver(ieOptions);
driver.Url = "http://cced.com/cced.aspx";
driver.Quit();
}
}
}
You can also refer to this official doc for detailed information: Use Internet Explorer Driver to automate IE mode in Microsoft Edge.
Update:
- If Protected Mode doesn’t exist in IE setting, you need to check it in registry. Please check
HKCUSoftwareMicrosoftWindowsCurrentVersionInternet SettingsZonesin registry, underZonesis a subkey for each zone:
- 1 (Intranet zone)
- 2 (Trusted Sites zone)
- 3 (Internet zone)
- 4 (Restricted Sites zone)
Under each numerically-named key, you can check or create a REG_DWORD value named 2500 to control Protected Mode for each zone. Setting that value to 0 enables Protected Mode; a setting of 3 disables it.
- It’s recommended to download and use 32-bit IEDriver. In my experience, there might be some issues when using 64-bit version.

I can suggest trying other ways to debug this code as it seams that it’s running locally and some things can go wrong in the enviroment configuration of the process.
first of all, check if the process running in the host http://localhost:9324/session/700c0df3-fcf5-459e-a9d9-0487cfd42d15/url is definitely available.
If so, try to increase the maxTimeout from your service’s http requests.
If both approaches do not work, add an try/catch exception for this whole block and try to understand more specifically what is going wrong to. If you figure out another exception, post it here.
